Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows:
Gravity dam panel is poured with without support punching block mounting structure, refers to Fig. 1-4, its practical novel point is:
Including the multigroup steel membrane 1 being sequentially arranged along dam length direction, multigroup punching block is arranged on outside the side of gravity dam bottom plate.
Every group of punching block by steel die 1-1, be welded in the steel die back side and form crisscross floor 1-2 and be welded on outside floor flat
Two longitudinal support beam 1-3 that row is set are formed, and longitudinal support beam uses i-beam structure, wherein positioned at two longitudinal directions on both sides
Floor aligns with two sides of steel die respectively, and the lower end of two longitudinal support beams extends to the lower section of steel die, such as,
Steel die using long 1.9m (L1), wide 1.5m (W1), thickness 12mm (S) steel plate, longitudinal support beam use I20 length for
3.9m (L2) I-steel, two longitudinal bracing case bays are 0.75m (W2), the upper end of longitudinal support beam and steel die it is upper
Hold with aliging, so, the length that longitudinal support beam stretches out from steel die lower end is 2m.In two longitudinal floors positioned at both sides
On be formed with longitudinally arranged multiple punching block connection preformed hole 1-2-1, it is close to top and vertical positioned at two in steel die
Punching block reinforcing preformed hole 1-1-1 is formed with to the position between support beam.
Have upper and lower two layers of the equal detachable connection in position for corresponding to every group of punching block in the sidepiece of gravity dam bottom plate 1 ' is overhanging
Reinforcing bar, specifically, protruding bar is the threaded bar construction in two, protruding bar is by the screw thread of one with being formed on gravity in advance
The screwed hole of dam bottom plate sidepiece forms detachable connection.Every layer of protruding bar is overhanging by least two arranged in the horizontal direction
Reinforcing bar 2 is formed.Two layers of protruding bar is located between two longitudinal support beams of corresponding punching block, wherein the protruding bar positioned at upper strata
Support is formed with the lower end of corresponding steel die to contact.The front of steel die is in contact with the bottom panel side of gravity dam, two
Wood block filler 3 is provided between the front of root longitudinal support beam and the bottom panel side of gravity dam, outside the back side of two longitudinal support beams
By forming clamping contact, upper strata with upper and lower two layers of protruding bar respectively provided with upper and lower two layers of holder, upper and lower two layers of holder
Holder 4 and lower floor's holder 5 can use the two suitable channel-section steels of root long degree.Correspond in two groups of clamping plate parts and often locate protruding bar
Position be mounted on pad 6 and the nut 7 being connected with the end of protruding bar by screw-threaded coupling, punching block is fixed on gravity
Outside the side of dam bottom plate.
Correspond at the top of gravity dam bottom plate at every group of punching block and be embedded with exposed steel bar 8, in punching block reinforcing preformed hole
Reinforcing reinforcing bar 9 is inside coated with, exposed steel bar is with corresponding reinforcing with connection reinforcing bar 10 is welded between reinforcing bar, in reinforcing steel
The face side that muscle is located at steel die is externally connected with nut 11, and nut preferably uses tapered cup nut at this, during in order to tear punching block open
Take out.Form the reinforcing holder 12 of clamping contact with reinforcing bar with reinforcing by being provided with outside the back side of two longitudinal support beams,
Reinforcing holder can use the two suitable channel-section steels of root long degree, and the position corresponding to reinforcing reinforcing bar outside reinforcing holder is equal
Pad 13 and the nut 14 being connected with reinforcing with the end of reinforcing bar by screw-threaded coupling are installed, make the upper end of steel die with
Formed at the top of gravity dam bottom plate and reinforce connection.
Adjacent two punching block forms detachable connection by the bolt 15 being threaded onto in corresponding punching block connection preformed hole.
In the above-mentioned punching block mounting structure without support:The punching block reinforcing being arranged on every group of punching block is preferably two with preformed hole
Individual, two punching block reinforcings are arranged in the horizontal direction with preformed hole, and two punching block reinforcings are separately positioned on close to two with preformed hole
The position of root longitudinal support beam.It is two, two to be arranged on the embedded bar corresponded at the top of gravity dam bottom plate at every group of punching block
Embedded bar is connected one by one with being installed on two punching block reinforcings with the reinforcing in preformed hole with reinforcing bar formation.
In the above-mentioned punching block mounting structure without support:The longitudinal floor for being welded in the steel die back side is preferably 3, and 3 vertical
To floor by both sides it is each one, it is middle one in a manner of be arranged, two longitudinal bracing mirror image beams are arranged at the longitudinal direction of centre
The both sides of floor.
Above-mentioned gravity dam panel pours as follows with the installation method without support punching block:
The first step:When carrying out gravity dam bottom slab concreting, in bottom plate sidepiece according to every group of punching block position is subsequently placed, up and down
Two layers of each pre-buried two reinforcing bar by screw thread process processing, while according to the position for subsequently placing every group of punching block at the top of gravity dam
Put, pre-buried exposed steel bar;After bottom slab concreting, the reinforcing bar of gravity dam sidepiece is removed, forms screwed preformed hole.
Second step:Block-by-block installs punching block, by punching block by admittedly outside the side of gravity dam bottom plate, installation steps are:
Reinforcing bar of the two all by screw thread process processing is first screwed into the preformed hole of gravity dam bottom plate sidepiece formation, formed a,
Protruding bar.
B, punching block is hung in into specified location with crane, makes the bottom shelf of steel die on the protruding bar of two, upper strata, and
Two protruding bars are placed between two longitudinal support beams.
C, two, upper strata protruding bar is clamped with two channel-section steels, two channel-section steels form upper strata holder, and put pad,
Fixation is tightened with nut, the suitable headblock of side thickness of the adjacent gravity dam bottom plate of two longitudinal support beams in rundown process
Block pad is good;It is in reinforcement connection, that is, is adopted by the way of same with the protruding bar of two, upper strata at two protruding bars of lower floor
It is fixedly connected with lower floor's holder, pad, nut and the wood block filler of cooperation.
D, the punching block reinforcing in steel die is with installing reinforcing reinforcing bar in preformed hole, with connection reinforcing bar by reinforcing steel
The exposed steel bar of correspondence position is by being welded to connect at the top of muscle and bottom plate, and uses spiral shell at the front preformed hole of steel die
Mother tightens fixation, using same with above-mentioned two protruding bars in upper strata at the back side reinforcing reinforcing bar of two longitudinal support beams
Mode be in reinforcement connection.
E, according to above-mentioned b-d installation steps close to another piece of punching block of installation, the punching block that blending bolt passes through punching block side
Two neighboring punching block is connected by connection with preformed hole, the like, until installing whole punching blocks.
